▎ 摘  要

NOVELTY - Preparing lithium-sulfur battery anode material involves generating reducing precursor elemental sulfur to reacted mixed solution, then reducing obtained precursor and oxide graphene solution to stir so that reducing precursor is oxidized to oxygen-containing functional group in oxidized graphene solution on graphene surface to generate elementary substance sulfur. The elementary substance sulfur is tightly adhered so that the graphene sheet elementary substance sulfur is packaged graphene. The graphene oxide in graphene oxide solution is partially reduced oxidation graphene. The mixed solution is mixed solution of hydrazine hydrate and N,N-dimethylformamide. USE - Method for preparing lithium-sulfur battery anode material. ADVANTAGE - The method enables to prepare lithium-sulfur battery anode material that has high specific capacity, good cycle performance and multiplying power performance.
